Lepthothrix organism. Medication course?

Last time i was sexually active was in September and it was protected, last time i had unprotected sex it was in July and I've had this infection since May. My periods are regular too. I was first told the infection that i have is a mixed infection because my symptoms were excessive vaginal discharge that one secreted became a string like nature, milky white in colour, chemicalised odour, burning sensation before and after peeing and random spotting occurred once or twice. I was on 3 treatments fas kit 3 (twice) and clingen forte (once) and cansoft and triben cream (once), i took tests and pap smear said i have lepthothrix and vaginal swab said i had nothing, i was on treatment for 14 days on nuforce CD 3, lacto bacilli and flagyl 400, i was on 8-9 Medications a day including my gastric tablets, it's been a week since i got done with my medications and my symptoms have not changed at all, infact it's more this time. Why has my infection not been cured after my medication course?
